Abstract

It is necessary for realization of comfortable cabin to achieve target spectrum of roadnoise. For this achievement, the authors specify seven eigenvalue of tire and clarify ideal eigenvalue according to combination of tire with suspension. This paper shows it is possible to control each tire eigenvalue with new tire analysis model and optimization technology.
